Compressed firmware image whose name only indicates a 32 MB capacity, with no device, brand or board number given. The ZIP is 13.4 MB, so the contained binary is probably a full 32 MB SPI flash dump that compresses well because of empty regions. Before using it, identify the target board by other means, confirm the flash chip on the PCB really is 32 MB (256 Mbit), and read and save the original chip contents with a programmer such as a CH341A. An image that does not match the chip size or the board will not fit or boot.</br>
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @vinafix_bios. Enginerys does not host this file.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
